Transient dynamic analysis of cracked magnetoelectroelastic composites by a hypersingular time‐domain BEM

Abstract

Due to the coupling effects between the mechanical, electrical and magnetic fields, magnetoelectroelastic (MEE) composite materials consisting of piezoelectric and piezomagnetic phases are receiving increasing attention in recent years [1]. The magnetoelectric coupling in the magnetoelectroelastic composite materials is much larger as compared to that of a single phase MEE material. MEE composites have many innovative applications in broadband sensing, actuating devices and smart structures, which are required in advanced engineering sciences and often subjected to dynamic like time-harmonic and impact loading conditions. The dynamic crack analysis is an important issue in material sciences and engineering applications of MEE composite materials. This paper presents a hypersingular time-domain boundary element method (TDBEM) for transient dynamic crack analysis in two-dimensional (2D), homogeneous, anisotropic and linear magnetoelectroelastic solids.
